[SPARK-11809] Switch the default Mesos mode to coarse-grained mode
Based on my conversions with people, I believe the consensus is that the coarse-grained mode is more stable and easier to reason about. It is best to use that as the default rather than the more flaky fine-grained mode.

Closes #9795 from rxin/SPARK-11809.
